I think that people care exactly as much for this fight as they did for the first 2.
Let me be very clear on this one, Dave: by "people" I mean "MMA fans in general". In the microcosm of the MHF, the first fight was a flashpoint that ignited long-standing tensions between Mike & GOAT. The "Great Schism" was not nearly as widespread across the entire MMA universe. Was it a close fight? Yeah. Was the decision argued? Of course. But only here was it such a gigantic issue & that's only because the rivalry between GOAT & Mike forced it to be so.
